Troy Bilt TB110 Spark Plug Replacement – Best Lawnmower Spark Plugs

Troy Bilt TB110 Spark Plug Replacement

Troy Bilt TB110 is a popular lawnmower with a Briggs and Stratton engine. It does not have a choke start or a simple prime. The lawnmower is built in the USA but its parts come from various parts of the globe. 

Many users love the lawnmower because it has a TriAction Cutting System, which gives the lawn an even and well-groomed look. It also works on rough spots and pushes through with ease. That’s something that not many lawnmowers can boast of. 

Just as is the case with any engine, over time the performance of this engine goes down as well. Wear & tear is one factor, of course, but faulty spark plugs tops the list. After a couple of years, you will need to change your TB110’s spark plugs for optimal performance and ease of use.
